GERENUK  , the Somali name of a

long-necked aberrant gazelle, commonly known as . Waller's gazelle (Lithocranius walleri), and ranging from Somaliland to Kilimanjaro . The long neck and limbs, coupled with peculiarities in the structure of the skull, entitle the gerenuk, which is a large species, to represent a genus . The horns of the bucks are heavy, and have a peculiar forward curvature at the tips; the colour of the coat is red-fawn, with a broad brown band down the back . Gerenuk are browsing ruminants, and, in Somaliland, are found in small family-parties, and feed more by browsing on the branches and leaves of trees and shrubs than by grazing . Frequently they raise themselves by standing on their hind-legs with the fore-feet resting against the trunk of the-tree on which they are feeding . Their usual pace is an awkward trot, not unlike that of a camel; and they seldombreak into a gallop . The Somali form has been separated as L. sclateri, but is not more than a local race . (See ANTELOPE.) GERGOVIA (mod . Gergovie), in ancient geography, the chief town of the Arverni, situated on a hill in the Auvergne, about 8 m. from the Puy de Dome, France . Julius Caesar attacked it in 52 B.C., but was beaten off; some walls and earthworks seem still to survive from this period . Later, when Gaul had been subdued, the place was dismantled and its Gaulish inhabitants resettled 4 M. away in the plain at the new Roman city of Augustonemetum (mod .

Clermont-

Ferrand) .
